In using this invention, the ends of the members'ofthe ring 10 are released at 2.0

and thrown back on the hinge 18, the jaws 34 bei'nghel'd 1i-n-"inoperative position by means of the latches 44. The devicelis then mounted upon the pipe, which is properly positioned by means of the rollers .100. The

7 parts of the ring 10 are then drawn-together and secured at 20. The latches 44 are then released by means of the levers 46, allowing the teeth 36 to come incontact with the pipe. Power is then appliedto drive the gearing 14 through the medium "of the worms. 30. This causes the teeth 36 to bite into the pipe, swinging slightly about the pivots 38 of the jaws 34. This is'continued until the pipe isturned as far as desired. The power. is then reversed for a moment in order to allow the teeth 36-:to be pulled out ot their fir m engagement with the pipe.-

Thisis necessary in order that the jaws 34 maybe thrown outof engagement manually by the 'levers 46 into position as shown in 'f desired,-the main drive shaft 7 2 may be extensible in order-to set the driving mechanism mounted on support 7 4 at a distance j from the housing 56. Itwill alsobe-neces' sary to provide some 'means,'such as the ,blockingshown in. Fig. 4, to support the housing 56 and take up the strain during operation. It will. be understood thatsuch *other bracing parts may be employed as conditions may demand.

'It will be understood, of course,.that I' do not wish to be limited to the specific form disclosed in the accompanying drawing, sincemanychanges may be made in 0011 struc tion' without departing from the invention as covered hr the claims appended hereto. i

I claim: .1. A pipe buck-comprising aring member I adapted to be positioned about a pipe, de-

vices on said; member to engage/the pipe during the turning operation, gear teeth." ;,forme,d 'on said ring member, worm gears, in

Tn-testimony turning the member converging shafts on engaging in said teeth at spaced points for said member.

which said worm gears are mounted, and a single drive shaft geared to said converging shafts. I

2. A pipe buck comprising a ring member,

movable means within said memberto engage a pipe for turning the same, brackets mounted upon said ring member carrying inner and outer rollers traveling upon inner and outer tracks on said ring member, said ring member having gear teeth thereon, and gear mechanism carried by said brackets and engaging said teeth for drivingthe ring member. Y

3. A p p'e buck comprising a rigid ring member, aws'wlthin said member and p1v-' oted'thereto, sald aws having teeth'.to"en-' gage a pipe for turning the same, means to engage and swing said jaws and hold them out of engaging position when the ring member is being applied, and means to turn 4. A pipe buck comprising a ring member adapted to be positioned about a pipe, devices on said member to, engagethe pipe during the turning operation, gear teeth formed on said ring member,-worm gears engaging in said teeth at spaced points for turning the member, shafts upon which said worm gears are mounted, a drive shaft".

geared to said shafts, and a flexible c tion in said drive shaft' j 5. A pipe buck comprising a ring member, movable means within said member to engage a pipe for turning the same, brackets mounted upon the ring, rollers in said brackets to engage inner and outer tracks on the ring member and thereby retain the brackets on the ring member, and means carried by the brackets foreng'aging and ing said ring member.
